I have filed for a divorce from my husband and moved into a hotel. I want to know if a hotel address is valid from immigration's perspective.

As long as you are holding valid H-1B visa status, you are entitled to live wherever you wish, even if it is in a hotel. You should inform U.S.C.I.S. of the change of address on form AR – 11. Insofar as other institutions are concerned, I believe that they would only be concerned if their mail was returned or if you did not pay on time.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
